Hepatitis A and hepatitis B infections occur seldom together owing to the fact that their transmission routes and common ages are different. Consequently, acute hepatit A infection can develop as a superinfection than a co-infection in chronic hepatitis B and C patients.

In this article, a case of acute viral hepatitis in which hepatitis A virus and hepatitis B virus acute serological markers were positive is presented. Male patient who was thirty three years old applied with jaundice, dark urine, anorexia, malaise, clay-colored stool.

There was no pathologic sign except from jaundice in the physical examination. Liver enzymes were elevated 60 times, prothrombin time was prolonged (16.4 sec), and total bilirubin was 15 mg/dl. HBs Ag, anti-HAV IgM, anti-HBc IgM and anti-HBc IgG were positive. Results were proved positive again when they were redetermined in the Reference Laboratory and ours.

In follow-up total bilirubin, direct bilirubin and prothrombin time drew back to normal range in the first month, and so did AST, ALT, ALP, GGT levels in the second month. Romatoid factor and anti-nuclear antibody were found negative related to false positivity about anti HAV IgM.

Consequently, in our case which have acute hepatitis A virus and hepatitis B virus serological markers were positive, did not differ from other hepatitis A or B cases in clinical and biochemical aspects.
